354-48-3 Usage
General Description
1,1,1-Tribromotrifluoroethane is a chemical compound with the formula C2HBr3F3. It is a colorless liquid at room temperature with a boiling point of 47 degrees Celsius. 1,1,1-TRIBROMOTRIFLUOROETHANE is primarily used as a fire extinguishing agent and as a refrigerant in some older refrigeration systems. However, it is also a potent ozone-depleting substance and has been phased out of use in many countries due to its harmful environmental effects. It is also considered a hazardous air pollutant and is regulated by government agencies. Exposure to 1,1,1-tribromotrifluoroethane can cause irritation to the skin, eyes, and respiratory system, and prolonged exposure can lead to more serious health effects.
Check Digit Verification of cas no
The CAS Registry Mumber 354-48-3 includes 6 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 3 digits, 3,5 and 4 respectively; the second part has 2 digits, 4 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 354-48:
(5*3)+(4*5)+(3*4)+(2*4)+(1*8)=63
63 % 10 = 3
So 354-48-3 is a valid CAS Registry Number.

The catalytic olefination reaction of aldehydes and ketones with CBr 3CF3
Nenajdenko, Valentine G.,Varseev, Georgy N.,Shastin, Alexey V.,Balenkova, Elisabeth S.
, p. 907 - 913 (2007/10/03)
The new approach of catalytic olefination reaction (COR) has been used to convert aromatic and aliphatic aldehydes and ketones to 2-bromo-3,3,3- trifluoroprop-1-enes by the treatment of corresponding hydrazones with CBr 3CF3 under copper(I) catalysis conditions. The reaction proceeds stereoselectively, the target alkenes were obtained in good yields.
